SPI NOR flashes need to erase the entire sector size and we cannot pass any arbitrary length for the erase operation. To illustrate the problem: Copying data from PC to DFU device Download [=========================] 100% 478208 bytes Download done. state(7) = dfuMANIFEST, status(0) = No error condition is present state(10) = dfuERROR, status(14) = Something went wrong, but the device does not know what it was Done! In this case, the binary has 478208 bytes and the M25P32 SPI NOR has an erase sector of 64kB. 478208 = 7 entire sectors of 64kiB + 19456 bytes. Erasing the first seven 64 kB sectors works fine, but when trying to erase the remainding 19456 causes problem and the board hangs. Fix the issue by always erasing with the erase sector size.
